Terrain texture won't change ANYWHERE

[Tetsune]

Every time I play around in Map maker, even with all the default Terrain and Masks and such, the texture won't change.
AT ALL.
It stays on the first texture no matter what I do.
I've tried changing ALL of the different layers, and nothing changes.

Please help?

EDIT:
It's not just the Map Maker.
It's everywhere.
There is only one texture I can see on the ENTIRE game.

Go to "Options," "Video," "Rendering Subsystem," and switch it.

Nope. Nada.
I already uninstalled/reinstalled COMPLETELY before, and it's still not changing.

UPDATE:
I realized that there is only ONE texture throughout the FeralHeart world, not just in my map making. :c
I don't know HOW this happened.

Then I'd suggest updating your graphics card.

I am having the same problem.  I think my boyfriend and I pretty much figured I need a new video card as well.  Good luck
